Application December 28, 1937, Serial No. 182,034

13 Claims.

My invention relates to a new and useful smoke purifier, which may be a part of a tobacco pipe or an attachment thereto, or may be used in connection with a cigar or cigarette holder. The present application is, in part, a continuation .of my prior copending application, Serial Number 98,542, filed August 29, 1936, and issued February 13, 1940, as Patent Number 2,190,312 and copending application Serial Number 165,451, filed September 24, 1937, and issued March 3, 1942, as Patent Number 2,274,889. The purpose of the invention is to provide improved means for absorbing the dust, oils, juices and other objectionable substances emanating either from the tobacco or the smokers mouth but especially the former. In addition it is an object to pass the smoke or smoke fumes through a liquid bath to condense, cool, sweeten and purify them and thereby prevent tongue burning and biting and give the smoker a pure, cool, sweet smoke.

In the past efforts have been made to provide a compact pipe adapted to hold liquid either vby having a receiving tube extended into the liquid or by placing an adjustable cap over the receiving tube to cause the smoke to flow in a reverse' direction and pass through the liquid. In the case where the receiving tube extends into the liquid, the tube itselfwill contain or hold a certain amount of liquid, and in some instances an inter-l mediate chamber was provided between the tobacco bowl and the liquid holding chamber to prevent leakage back to the tobacco bowl. w such a case the receiving or induction tube in the liquid chamber was placed directly over or in alignment with the tube projecting from the tobacco bowl and naturally any liquid that would ilow back and down the receiving tube would drop into the tube leading from the tobacco bowl and wet the tobacco. In the case of the oating, movable, adjustable, condensing cylinder or cap, no provision was made to prevent leakage when the pipe was inverted. Generally pipes are held in the mouth substantially horizontally, possibly slightly tilted forwards or backwards, or vertically, or in various other positions, which is bound to be done by the smoker when carried in either the hands or pocket, and it is important that leakage be avoided as well as to have the liquid fall to its proper place when the pipe is put into the mouth for smoking. In the case of intermediate chambers between the liquid holding chamber, the tobacco bowl and the mouthpiece, it means that the liquid entering these chambers must be returned to the liquid holding chamber to make the liquid seal function for the purpose intended.

As can be realized, this would be bothersome and cumbersome because in tilting the pipe upside down to get the liquid from the lower chamber to the liquid holding chamber, the tobacco and ashes would fall out and annoy the smoker. the case of an open end condensing cylinder, when the pipe is in a horizontal position and the liquid is below the top outer open end of the cylinder, the smoke following the line of least resistance would escape without passing through the liquid. Also in the case of an open end condensing cylinder that is oating, movable or adjustable, the condensing cylinder will have a tendency to move with the liquid and as some'of the liquid is con- Itained in the condensing cylinder, when the pipe is turned upside down, part of the liquid will rest in the cylinder or cap and when the pipe is righted this liquid will flow down the receiving or induction tube wetting the tobacco.

In my prior application, Ser. No. 165,451, dated September 24, 1937, the ob-ject of sealing the outer end of the condenser cylinder and puttingthe opening or spout on the bottom was to get a low liquid seal, low enough if desired, so that no liquid would be contained in the condenser cylinder. In this instance the transverse ports were used to get the smoke from the receiving tube to the condensercylinder and the sealing, of the far end of the receiving tube with the inner end of the condenser cylinder was to preventv leakage to the tobacco bowl when the pipe was inverted. Also due to the fact that there is a certain amount of moisture, oils and juices con tained in most tobaccos, the flowing of the mois- V ture, oils and juices to the liquid holding chamber, when the tobacco is being smoked continuously, that is one pipeful after another, has a tendency to increase the volume of the liquid in liquid holding chamber. To partially prevent or practically overcome this condition, an absorbent lter cartridge is'used and while the use of an absorbent filter cartridge in itself is not new, it produces a novel combination in conjunction with other elements of the present purier. The provision of a groove for easy removal of the lter cartridge and the association of said iilter cartridge with the liquid holding cartridge as a part of a unitary purier structure is beneficial and helpful to a smoker.

Further it is natural for a smoker to tilt his pipe forwards or backwards while it is being held in the mouth. When the pipe is tilted backwards, themouthpiece stem is so bored as to form a barrier or dam and produce a well or reservoir to retain the liquid in proper position and maintain It is very important that the `proper amount of:

liquid to be put in the purier be known so that the purifier may operate successfully. There'- fore a liquid holding cartridge is provided con` Another object of the present invention is the provision of a purier of one-piece construction having absorbent material on each end to catch or hold the juices from the tobacco at one end and to catch or hold the saliva, which flows through the mouthpiece tube from the smokers mouth, at the other end.

Another object is the use of an intermediate space or chamber between the outer wall of a pipe bowl shank and a unitary purifier cartridge so as to cause the smoke to drag and deposit slugs of tobacco, dust, juices and other substances on the bottom of the shank and absorbent end wall of the cartridge before entering the taining the proper amount of liquid to be put Ain the purier or the cartridge' may be' used to indicate the quantity of liquid to be put :in the r Y purifier as a rell, as successive changes of liquid are needed to purify the smoke.- i

It is also very important that a means for re-" moving the discolored liquid be provided and' the'y liquid holding cartridge is used for this purpose. A fter the liquid has been drained into the liquid holding cartridge, either while the cartridge is partly in the mouthpiece stem' or after the cary tridge has been removed, and said cartridge finally withdrawn, it may be capped with a cap from Y a new cartridge and thrown away. The capping of the cartridge to be discarded seals the same and prevents the escape of any unpleasant odor or the actual liquid which might destroy or damage property.

Naturally the simplest and easiest device to use to obtain a cool pleasant smoke is the purifier cartridge of a unitary structure, but some smokers prefer the blending of the juices from the tobacco that come in contactwith the liquid in the purier, while others prefer changing the liquid after each pipeiul of tobacco. In the lat-" i ter case, an inexpensive removable cartridge is" used and if the smoker does not want to -use a discardable cartridge, the cartridge may be made of more durable material and used for inserting and withdrawing the liquid.

The general object of the invention is to provide a novel construction of tobacco pipe stemy and a cigar'or cigarette holder stem so that in an assembled purifier a reservoir for the sealing liquid will be provided from which said liquid may be easily removed. In the case of a purifier made ina unitary structure, the construction of the stem is such that the purifier cartridge, which may contain a reservoir, may be inserted and removed with ease.

,Another object o f the invention is to provide a liquid holding cartridge which forms apart of the purifier, said .cartridge having a closed end and an open end, the latter facing the tobacco bowl. This arrangement requires the use of only a cover and eliminates the use of extra plugs or closures to hold the liquid in the cartridge until ready for use or to hold vthe `liquid that is to be thrown away.

Another object is the use of an attachable removable combination unit that consists of an absorbent iilter cartridge and a cylinder. The cartridge being divided into'two sections by a seal, the primary'section making connection to the tobacco bowl and being enclosed by the cylinder andthe secondary section making connection to the mouthpiece tube. The cylinder being capable of holding liquid for insertion into or removal from the smoke purier.

passageway of the unitary purier cartridge.

Another-object is, the use of a pipe bowl that,

` has a recess on its bottom so that the pipe may rest comfortably between the thumb and forenger ofthe smokers hand when the pipe is not being smoked. The shank of this same pipe bowl may also contain `a deeper and better well than could be obtained with-a straight horizontal l pipe bowl, stem or shank that did not have a recess in it.

Another object is the use of a cover cap for a liquid holding cartridge that may be used for placing on the end of a mouthpiece stem for draining the liquid from a liquid holding pipe or purifier.

AnotherL object is the novel-construction of a pipe bowl shank so that the inner end of the cylinder or liquid holding cartridge or the holder for the liquid holding cartridge closes the shank bore except for a channel on the bottom for the smoke to pass. This channel opening is to contain a liquid seal l Anotherobject is the use of an insertable bowl and placing the liquid seal or orice opening near the outer end ofthe tobacco bowl so -that the pipe maybe smoked in a vertical position and retain the liquid seal. l

vAnother. object is the use of a combination mouthpiece stem for a tobacco pipe, cigar or cigarette holder that may be used to hold a unitary puriiier cartridgefor which may be used to hold removable purifier parts.

Another object is the alignment of the receiving tube with the tube from the mouthpiecewith the removable cylinder carried by the mouthpiece tube so that when the cylinder which seals the receiving tube is removed and the mouthpiece is put in the pipe Without the cylinder, a cleaner may be inserted to clean both the receiving tube and the mouthpiece tube.

For identication purposes, the puriiier of onepiece construction is called a purifier cartridge. Where the` purifier is a part of the pipe stem or cigar or cigarette holder and h as removable parts, the center or receiving tube communicating -with the tobacco bowl is referred to as the absorbent filter cartridge while the tube or condensing cylinder that surrounds or encloses the filter cartridge istermed the liquid holding cartridge. The combination unit consists of an absorbent iilter cartridge and a condensing cylinder with the absorbent filter cartridge divided into two sections by a seal, one section making connection to the tobacco bowl and the other with the mouthpiece tube. In some instances the center tube may be of other than absorbent material and the liquid holding cartridge may be permanently attachedto the mouthpiece tube instead of being removable. Where the cylinder is used merely as a condenser it mayl include absorbent material.-

With the above and other objects in view, this invention consists of the details of construction and combination of elements hereinafter set forth and then designated by the claims.

In order that those skilled in the art to which this invention appertains may understand how to make and use the same, I will describe its construction, referring by numerals to the accompanying drawings, in which:

In carrying out the invention, particular reference being first had to Figs. l to 4 inclusive, 25 represents a tobacco bowl having a tobacco chamber 25 with a draft opening 2'! leading therefrom land communicating with the interior' of the pipe shank 28. This shank has two bores 2S and 30, one eccentric to the other, thereby forming a shoulder 3l and the outer end of said shank is preferably reduced in circumference at its outer end as indicated at 32.

A pipe stem 33 is fashioned to provide a socket 34 to fit over the reduced end 32 of the shank 28, an intermediate portion 35 of smaller diameter than the socket 34 so the inner surface of said intermediate portion is flush with the inner surface of the contiguous end of the shank, and a small socket 3B to receive the mouthpiece 31 the latter having a bore 38. The formation of the sockets and intermediate portion provides a shoulder 39 to engage the end of the shank 28 and another shoulder 40 for a purpose to be later described. While the mouthpiece 31 is shown as separate from the pipe stem 33 they may be made as an integral unit. It might be well to state at this point that while the part .28 is referred to as a shank and the part 33 is mentioned as the pipe stem the two together actually form the stem of the pipe.

The purier cartridge 4I includes an outside tube or body 42 of specially treated liquid proof paper, glass or other suitable material with absorbent or partly absorbent end walls 43 mounted in the ends of said tube or body. For purpose of illustration these end walls are shown as each including a disc 44 of liquid proof paper or equivalent material and a pad 45 of absorbent material. Each of said end walls has a hole 46 therethrough forming parts ofthe draft passage way.

Central filter cartridges 41 and 41a are positioned between the end walls 44 with the bores of the filter cartridges in registration with the holes 46 and said filter cartridges have a partition or obstruction 48 between their contiguous ends with sets of lateral openings 49 and 56 so located that one set is to one side of the partitition and the other set is to the other side of the said partition. Each central filter cartridge consists of an outer jacket 5l of water proof paper or equivalent material 'and an inner layer 52 vof absorbent material.

About the outer end of the central tubular member or filter cartridge 41 is a condenser cylinder 53 of paper, composition or other material which encloses only the set of openings A49 and one end of this condenser cylinder coacts with one of the end walls 44 and the other end of said cylinderhas its own end wall 54 which engages the filter cartridge 41.l At the bottom of the condenser cylinder 53 adjacent its outer end or that end which lies adjacent the pipe bowl is formed an outlet orifice 55 to bel sealed by a liquid sealing medium contained within the purifier cartridge and particularly in the outside tube or body 42. In'order that a' small quantity of liquid may be used for sealing purposes and that said liquid be confined in a limited space, a dam or barrier 5S is provided which Ymay be an integral projection on the condenser cylinder or va separate piece of material at the closed end of said condenser cylinder. Said dam or .barrier engages the lower portion of the outer tube or body 42 to provide a well 51 for the sealing liquid. The purifier cartridge 4I has an end partially cut away or formed with a recess 58 to coact with the shoulder3l whereby said purifier cartridge can be placed in the pipe stem in only one way, that is, with the orifice 55 at the bottom of the device and positions the recessed end of the purifier cartridge so that a space 59 is provided between said recessed end of the cartridge and the contiguous wall of the pipe bowl. This intermediate space or chamber 59 causes the smoke to drag and deposit slugs of tobacco dust, juices and other substances on the bottom of the shank 23 before entering the hole 45.

With sufficient liquid sealing medium in the well 51 to seal the orifice I55 when the smoker f draws on the pipe, the smoke passes through the draft opening 27 into the Chamber 53 contacting the absorbent material adjacent the pipe bowl where some of the juices from the tobacco will be taken up. From the chamber 59 the smoke will pass through the hole 46 thence through a portion of the filter cartridge 41 where additional juices may be absorbed. Next the smoke passes through the set of openings 49 into the condenser cylinder where .it is caused to .reverse and ow downwards to reach the orifice 55. As the smoke departs from the condenser cylinder through the oriiice it is drawn through the liquid seal and caused to iiow through the set oi openings '50 then through an additional portion of the filter cartridge 41 then through the hole in the other end closure and iinally through the bore of the mouthpiece into the smokers mouth. Any saliva passing down the bore of the mouthpiece will be caught by the absorbent material contiguous said mouthpiece or by the filter cartridge. It will be obvious that the pipe may be tilted or turned in various positions without the sealing liquid reach ing either the pipe bowl or the mouthpiece and therefore such a pipe may be carried in the pocket or other receptacle without the danger of losing the liquid or aifecting the smoking qualities of the pipe. When it is desired to discard the puriiier cartridge and replace it with a new one, the pipe stem 33 is removed from the pipe shank 28 exposing one end of said purifier cartridge which may be grasped by the hand and withdrawn from the pipe stem and thrown away. A new purifier cartridge with fresh liquid is then placed in position by reversing the above operations.

In the modiiication illustrated in Figs. 5 and 7 the reference numeral Sli designates the pipe bowl of plastic, glass, specially treated wood or other suitable material with a draft opening 5I. This bowl has a shank 62 not like Fig. l, but one with a recess so as to form a better well in a horizontal pipe, The well is formed between the shank and shoulder 1li mentioned later in this specification. The recess 52a on the outside of the pipe permits the pipe to rest comfortably between the thumb and the forenger when carried in the hand.

A smaller concentric tubular projection 83 is formed within the shank, said projection 63 having a slot '64 formed in its lower side to provide an outlet orifice as will be apparent from later description. The pipe bowl may or may not be provided with an insertable tobacco bowl 65 of clay, briar wood or other suitable material which would have a draft opening 66.

In the draft opening is a short tube 61 preferably of compressible material and this tube supports an end of the absorbent lter cartridge B8 when the latter is slipped over said tube, although said absorbent filter cartridge may be made small enough to t into the tube. Like the other filter cartridge, the present one may include an outer jacket of waterproof paper and an inner layer of absorbent material. A groove 59 is made in the outside near one end and lateral openings 10 are formed in the sides of said filter cartridge intermediate the ends thereof. A condenser cylinder 1l which surrounds that portion of the iilter cartridge G8 beyond the tubular projection 53 has a closed end to engage an end of said iilter cartridge and an open end telescoping over tubular projection 63 a short distance but leaving a part of the slot t4 uncovered for the passage of the smoke. This condenser cylinder also functions as a liquid holding cartridge.

On the shank 62 is mounted a secondary shank 12 having a reduced end to form a nipple 13 and provide a shoulder 14 which is engaged by an end of the stem 15 when the latter is placed on said nipple. If desired, the shoulder 14 may also be used to form a well. The mouthpiece end of the stem 15 is reduced to form a neck or socket 16 and provide an offset or shoulder 11. The neck or socket is adapted to receive the inner end of the mouthpiece-18 Aand also has one end of a sleeve 19 mounted therein Whichsleeve is of suicient length to pass over the closed end of the condenser cylinder and assist in holding the latter in place. The -sleeve being of smaller diameter than the main body portion of the stem 15 provides a space between them for passage of smoke towards the lateral openings in said sleeve adjacent the closed end of the condenser cylinder. A tube 8l' is carried bythe inner end of theimouthpiece and the bore of said tube communicates with the bore 82 of said mouthpiece. This tube projects into the sleeve 19 and has its outer end closed adjacent which there are lateral openings 83.

With sufficient sealing liquid in the stem and component parts to seal the oriiice provided by the uncovered part ofthe slot 64, when the pipe is drawn upon, the smoke will iiow through the draft opening or the tube 61, the filter cartridge $8, the openings 10, the condenser cylinder, the slot @11, then passing through the liquid seal and the openings 83 into the sleeve 19, afterwards iiowing through the openings 83 into the tube 8l and iinally passing through said4 tube and the bore of the mouthpiece to the smokers mouth.

In this particular arrangement the purier is considered a part of the pipe and has removable parts so that upon withdrawal of the stem, sleeve and condenser cylinder a portion of the lter cartridge is uncovered vand-may be readily removed by engaging the fingernail, a coin or other instrument in the groove 89 to pull said lter cartridge oi of the tube 81.v The staggered locations of the several openings prevents the sealing liquid from flowing directly from one chamber to another and the spacing of said openings from the ends ofthe chambers prevents theliquid from overflowing from one chamber to another so the pipe can be held and carried in any position without hesitancy and the liquid will always return to a position to seallthe slot 64 when the pipe is to be used;

The condenser cylinder 1l can be used to hold a vquantity of sealing liquid by placing a cap over its open end when not in the pipe and also may be used to receive the discolored liquid Aand when capped can be discarded Without the liquid coming in contact with the person or any property. As the closed end of said condenser cylinder is partially enclosed in the sleeve 19 while the purier is in use such enclosed portion will remain in a clean condition so as not to soil the fingers when said condenser cylinder is removed.

Figs. 6 and 8 illustrate the pipe bowl 84 as having a shank 85 on which the stem 8S is mounted and this shank has a tapered bore 81 to which leads the draft opening 88 and from which leads the outlet oriiice 89 to an external recess 90. 'Ihe recess provides a space between the shank and stem for passage of smoke and the reception of sealing liquid to seal the orifice. This construction is especially advantageous because a very small amount of sealing liquid is required to seal the outlet orifice which terminates Very close to the bottom of the stem. A tube 9| is in the draft opening to receive and support one end of the filter cartridge 92 the same as previously described. The condenser cylinder 93, which also may be used as a liquid holding or measuring instrumentality is placed about the lter cartridge and the open end of said cylinder forced or wedged into the tapered bore 81 to retain the cylinder in position. An

insertable tobacco bowl 94 may be used if desired but is notabsolutely necessary. The balance of the'pipe may be constructed in accordance with any illustrated formation but'particularly that shown in Fig. 16.

The modification illustrated in Figs. 9 to 13 inclusive has many features of similarity to that shown in Fig. 5 and therefore is considered as a part of the pipe and with removable parts. The structure disclosed includes a pipe bowl 95 with an integral shank 96 which may be made of briar wood or other suitable material. To prevent leakage a cup 91 of plastic or other suitable substance is placed in the shank with the end Wall of said cup adjacent the pipe bowl and said end wall has a hole 98 in alignment with the draft opening 99. Formed with or carried by the cup is a tubular projection having a spout |0| at the bottom to provide the outlet oriece |02 and said spout terminates very close to the lowof sealing liquid is required to seal said outlet orifice.

A tube |03 is mounted in the draft opening and extends through the hole 98 to receive one end of the absorbent filler cartridge |04 of the;

same construction as those before referred to and having lateral openings |05. `As previously described, the lter cartridge, Fig. l2, preferably comprises an outer jacket |06 of water proof paper or equivalent material and an inner layer of absorbent material |01.

A condenser cylinder and liquid holding cartridge |08 is designed to enclose the filter cartridge |04 and telescope over the tubular projection |00. In a combination unit, said cylinder has a, closed end provided with a lug |09 which, for purposes of illustration, Fig. 13, is shown as a plug inserted in the closed end ,of the cylinder to support the opposite end of the lter cartridge. This condenser cylinder and filter cartridge may be mounted in a holder ||0 including a ring lil on the outer ends of the arms ||2 of the U-shaped support ||3. The holder has a lug ||4 projecting from the cross bar of the U-shaped support and entered into the tube carried by the mouthpiece H6. In such a construction the condenser cylinder and liquid holding cartridge |08 may be of cheap or .inexpensive material, however, should the cylinder be of more substantial or more expensive material, the holder ||0 may be dispensed with and said cylinder carried by the mouthpiece structure, being formed with or detachably Yconnected to the tube ||5. This tube ||5 will be closed at its outer end but has lateral openings leading to the bore of the tube which bore` communicates with the bore ||8a of the mouthpiece.

The stem I8 is mounted on the shank 96 and has a reduced inner end ||9 which the holder ||0 or the cylinder |08 will snugly fit and this reduced end receives the mouthpiece I I6. In the formation of the reduced end of the stem a shoulder is provided that establishes one end of the well for the sealing liquid. If desired, a smaller shoulder like |20 may be placed nearer the orice opening |02.

When using the pipe, smoke passes from the pipe bowl through the tube |03 into the filter cartridge |04 and then out through the openings |05 into the cylinder |08 and back to and through the outlet orice 02. As the smoke enters the stem ||8 it passes through the sealing eral openings ||1 nally following through the bore of the mouthpiece to the smokersmouth.

Inl removing the sealing liquid, especially after it has been discolored, the pipe is tilted so the bowl is downward and the mouthpiece is slowly withdrawn from the stem until the cylinder |08 is pulled into the reduced end of the stem a sufficient distance to bring the open end of said cylinder fiush with or beyond the shoulder 20. The pipe'is then inverted causing the liquid to ow into the cylinder. If the cylinder is in a holder i I0, said cylinder is partially ejected, capped with a cap iZ, see Fig. 13, preferably from a new cylinder, and taken from the holder and discarded. `Of course, it will be obvious that, if

, desired, the mouthpiece and associated elements er part of the cup ange whereby a small amount...

liquid and enters the tube ||5 through the lat- 76 can be removed and the liquid poured from the stem into the cylinder or other receptacle or otherwise disposed of.

Further the liquid holding cartridge |08,Fig. 13,

need not be a part of the pipe and may be a plain liquid container without the absorbent filter cartridge and the flange of its cap |2| made so as to fit over lthe small end, as ||9 Fig. 9, of a pipe stem to rst receive the liquid to be discharged. This cap is obtained from a new cartridge containing fresh liquid. When the liquid is in the cap the latter is removed from theA stem and set aside. Next the fresh liquid is poured into the pipe stem and the disengaged parts reassembled and then the liquid is poured from the cap into the liquid holding cartridge and nally said cap vis used to close the cartridge to prevent spilling of the liquid therein as the Whole thing is thrown away or otherwise disposed of.

Where the cylinder is constructed to remain a part of the purifier, the said cylinder is merely cleaned and the discolored liquid replaced.

The form of the invention embodied in Figs. 14 and 15 includes a stem |22 with a mouthpiece |23 having a bore |24 mounted in one end and a connector |25 at the other end. A connector |25 may be of the plug type as shown in Fig. 14 or of the socket type as in Fig. 15. The plug type of connector is especially designed for cooperation with a pipe bowl |26 while thesocket type is adapted to receive and hold a cigar or cigarette.

By making the connectors detachable from the stem they may be interchanged and theV purifier then used for either purpose. Each type of connector has a bore |21.

A tube |28 is mounted in the bore of the connector and is located wholly within the stem |22 along its axial center. Surrounding the intermediate portion of the tube is a cylinder |29 open at its outer end and having an inner end wall provided with an outlet orice |30 in the bottom side. A dam or barrier I3 is located between the bottom sides of the stem and cylinder and may be formed'with or attached to either of them so as to provide a well |32 in the bottom of the stem at the connector end. The tube and cylinder may be made of the samepiece of material or they may be separate parts fastened 'together as will be obvious. Said tube |28 has lateral openings |33 located anywhere between the inner end of the tube and the closed end of the cylinder but preferably outside of said cylinder .to permit ready access thereto for cleaning purposes.

A tube |34 is carried by and projects from the inner end of the mouthpiece |23 and the bore of said tube |34 communicates with the bore of said mouthpiece. The inner end of the tube |34 is closed in any suitable manner, as by a plug |35, but has lateral openings |36 to provide communications between the interior and exterior of said tube.

A cylinder |31 may be detachably fastened to the tube |34 in any suitable manner so as to be removed, for example the outer end of the cylinder, as shown in Fig. 15, may have a lug |35a with a nib |3512 attached to the lug for engaging in a bayonet slot |34a on the outer end of the tube |34. The cylinder is closed at its outer end Where it joins with the tube and open at its inner end.

The cylinders |29 and |31 telescope, one over the other, and for purposes of illustration, the

cylinder |31 is shown large enough to fit over the cylinder |29. When the parts are assembled the contiguous ends of the tubes |28 and |34 will be closed and the combining of the two cylinders will produce an inner chamber |38.and t an outer chamber |39. A sealing liquid is placed in the well |32 so as to liquid seal the outlet orifice |30 and when the device is in use for smoking purposes the smoke from the tobacco will flow through the tube |28, through the openings' |33,

in a reverse direction through the chamber |38 to the outlet orifice |30, through said orice into the chamber |39. As the smoke enters the chamber |39 it is compelled to pass through the sealing liquid before owing through the openings |36@ and the bores of the tube |34 and the mouthpiece |23 to the smokers mouth. Sealing the inner end of the cylinder |29 and using a spout for the outlet orifice and the formation of a well by the barrier or dam `13| will require only a small amount of liquid to seal the outlet orifice |30.

In the modification in Figs. 16 and 17, a pipe bowl |40 is provided with a shank |4| having a large bore |42 with a rib |43 extending around the top and down the side of the bore |42 but not along the bottom thus forming a channel |44 between the adjacent ends of the rib and forming a communicating passageway between the pipe bowl and the large bore |42. A stem |45 is mounted on the shank and has a tapered or funnel shaped portion terminating in a socket end |46 to receive the mouthpiece |41 provided with a bore |48. In lieu of the shape illustrated in Fig. 16, the stem may be made like that shown in Fig. 18.

A tube |49 having lateral openings |50 is attached to the inner end of the mouthpiece |41 With the bores thereof in communication. On the inner end of the tube |49 is mounted a holder |5| thus closing said inner end of the tube |49'.I4

Said holder is like the one previously described and includes a ring |52 on the outer ends of the arms |53 of the U-shaped support |54. A condenser cylinder and liquid holding cartridge |55 is mounted in the holder |5|, and holder ringl` and the open end of the cylinder are inserted in the smaller bore |56 formed by the rib |43 thus providing a tight joint With the channel |44 as the only communication between the interior of the cylinder |55 and the interior of stem |45.

The cylinder may have a lug |51 on its closed end to receive one end of the absorbent filter cartridge |58 while the other end of said filter cartridge is slipped over the induction tube |59 herein shown as projecting from the draft opening of an insertable tobacco bowl |60. The filter cartridge, like those formerly described, comprises an outer jacket |6| and an inner layer of absorbent material |62 and said lter cartridge has lateral openings |63 intermediate its ends providing communications between the interior of the cartridge and the cylinder. This construction of purifier eliminates the sleeve or other tubular extensions required in the other structures and provides a relatively largechaniber in thejstem to allow the smoke to slow down and become cool before entering the smokers mouth.

With sufficient liquid in the shank |4| and the outer portion of thegstem |45 to fill, at least, the channel- |44, when the .pipeis drawn on, the smoke will travel through the tube |59 into the lter cartridge |58 and out; of thev openings |63 into the cylinder |55 where'the smoke is caused to ow in a reverse direction and out of the open end of said cylinder. From this location the smoke must pass through the sealing liquid as it travels through the channel |44 to reach the chamber within the stem |45 from which chamber 'it flows through the openings |50 into the tube |49 finallyypassing through said tube and the bore of the mouthpiece tothe smokers mouth. A pipe fitted in this manner can be smoked in a substantially vertical position withoutl fear of the liquid receding from the channel constituting the outlet orifice. h

To withdraw the holder |5| and theparts carried thereby. the mouthpiece |41 is separated from the stem |45 and the'ring |52 of the holder pulled into the socket |46ffrom which the mouthdiscarded. New liquid contained in another cylinder can be emptied into the stem or a liquid measure by the cylinder can be poured into said stem and said cylinder inserted in the holder and the parts replaced. As is obvious, the insertable bowl may be eliminated, if desired.

In the modification illustrated in Figs. 18 and 19 a pipe bowl |64 has a shank |65 with a large bore |66, the latter communicating with the interior of the pipe bowl through a smaller bore |61. A draft orifice |68 leads from the interior of the pipe bowl adjacent the front portion of said bowl to the duct |69 opening into the larger bore of the shank. On the shank is mounted the stem |10 having a large portion to fit over the shank and a small portion to receive the mouthpiece |1I.Y `The interior diameter of the small land has lateralA openings |14 intermediate the ends thereof. On the inner end of the tube |13 is mounted a holder |15 including a ring |16 on the outer ends of the arms |11 forming a part of the support |18. c

In the holder is removably mounted the condenser cylinder and liquid holding cartridge |19 with the'open end of said cylinder flush with the outer edge of the holder ring so that when the latter is positioned at the smaller bore |61 a joint is made between the holder and the cylinder therein and the pipe walls. The closed end of the condenser cylinder |19 has a lug |80 to register with one end of the absorbent filter cartridge |8| which is the same as in Fig. 16. The other end of the filter cartridge |8| slips over the compressible tube |82 mounted in the draft opening of the tobacco bowl |83. Said filter cartridge has lateral openings |84 intermediate its ends.

Assuming there is sufficient liquid in the device to ll the duct |59 when the pipe is being smoked, the smoke will travel through the tube |82, the filter cartridge I8|, the openings |84, the passageways between the filter cartridge and the cylinder and between the tobacco and pipe bowls, the outlet orifice |98, passing through the sealing liquid in the duct |69 into the stem, thence through the openings |74, the tube |73 and bore |12 of the mouthpiece to the smokers mouth.

This construction places the point of liquid sealing well to the front of the' pipe and therefore such pipe may be smoked in an almost vertical as well as other positions and still retain the liquid seal.

The modication illustrated in Figs. 20 and 21 includes a pipe bowl |85 with a shank |86 having a large bore |81, an intermediate bore |98 and a smaller bore |89 provided with a flat portion |89a. The walls forming the intermediate and smaller bores are provided with notches |89b. On the shank is mounted a stem |90 fashioned to provide a socket |9| and a reduced mouthpiece receiving end |92 with a shoulder |93 between them. In the end |92 is mounted the mouthpiece |94 having a bore |95 and provided with an integral sleeve |95 to receive one end of the puriiier cartridge |91. This puriiier cartridge includes an outer tube or body |96 having end walls |99 with a layer of absorbent material 290 on their outer surfaces. Each end wall, including the absorbent material, has a hole 20! therethrough. A condenser cylinder and liquid holding cartridge 202 is located within the body |98 at the end adjacent the pipe bowl and the open end of said cylinder is partially closed by the coacting end wall |99 and in the bottom wall is formed an outlet oriiice 203. At the closed end of the cylinder 202 is a barrier or dam 204 providing a liquid well 295. Between the forward end wall |99 and the closed end of the cylinder so as to be situated within said cylinder is a iilter cartridge 296 having lateral openings 201 intermediate its ends. W'hen the purifier cartridge I9? is placed in the pipe, the lter cartridge 206 telescopes over a long induction tube 208 mounted in the draft opening 299 of the pipe bowl and said tube 208 has lateral openings 2|0 to register with the lateral openings 207. A secondary filter cartridge 2|| is mounted outside of the cylinder 202 between its closed end and the rear end wall |99 of the purier cartridge with the bore of said secondary iilter cartridge in registration with the hole 29| in said rear end wall. The secondary lter cartridge has lateral openings 2|2 adjacent the closed end of the cylinder 202 which closed end seals the inner ends of both the primary and secondary lter cartridge.

In order to insure proper placement of the purifier cartridge |97 in the pipe, the forward end of said purifier cartridge is fashioned to provide a flat portion 2|3 for coaction with the flat |89a. In this position the openings 207 and 2|0 will be in alignment and the orifice 203 will be at the bottom of the device whereby smoke may travel in the desired directions from the bowl to the smokers mouth.

It will be observed that upon removal of the unitary cartridge |91, the receiving tube 208 remains attached to the appliance, and a cylinder and plug, similar to the cylinder |08 and the plug |99, Fig. 13, may be mounted on the receiving tube 208 and with the mouthpiece 90 reattached to the appliance, said appliance maycontain'and be smoked with a removable condensing cylinder.

It is to be particularly noted that where a liquid holding cartridge is not used as a storage member having a denite quantity of liquid therein such cartridge may be of such a size that it can be used as a measuring instrument to determine the pro-per amount of liquid to be placed in the purifier as a liquid seal.

It will be observed that the location and arrangement of the several openings is such that the pipe, cigar or cigarette holder may be used in any proper or near proper smoking position and a liquid seal will be positively maintained and the sealing liquid can flow around and about the device, as said device is placed in various positions, without the liquid reaching either the tobacco or the smokers mouth when the device is subsequently used.

As will be also noted, there are variousways of using a condensing cylinder to form or contain an outlet orice. f
